TO BE PERFECTLY HONEST , IT REALLY DOESNT MATTER WHAT KIND YOU USE AS LONG AS THE GRAIN STAYS AT 100 GRAINS OR LESS WITH CARBON ARROWS. MECHANICALS WORK WELL WITH MINE. I SHOOT A FRED BEAD EPIC EXTREME WITH CARBONS AND USE 100 GRAIN GAME TRACKERS. SOME PEOPLE WOULD DISAGREE THAT IT DOESNT MATTER , BUT IT DOESNT AS LONG AS YOUR BOW IS TUNED.
